Sliding Fifth Wheel Installation - ILS Slider
Prior to proceeding with the installation of the sliding fifth wheel assembly,
carefully review the “General Safety Information” section on page 2.
Inboard Angle Mounting
(See Figures 3 and 4):
1. Angles must be installed on the
sliding fifth wheel base plate
plate to facilitate mounting.
See “Installation: General
Recommendations,” on page 3,
for angle thickness and material.
2. Use a mounting angle which is at
least 2˝ longer than the slide base,
36˝ minimum length, and 3-1/2˝
minimum vertical leg size. For
horizontal leg size, see
TABLE 2.
The fifth wheel top may be
removed from the base plate
for ease of handling.
3. Position the angles on the slide
plate for the required frame width.
Be sure to keep the plate centered
left to right, and front to rear on
the mounting angles.
4. Weld as shown in FIGURE 3.
Outside welds to have a 3/8˝ fillet
weld placed either on or between
the tabs, depending on frame
width. Inside welds to be 3/8˝ fillet skip weld alternating with the outside welds so
that they are staggered along the angle. Also weld the fifth wheel base plate to the
top of the angle at the ends of the plate as shown in FIGURE 3.
5. Attach the slider plate and mounting angles to the tractor using recommendations
in “Installation: General Recommendations,” on page 3 and in FIGURE 4.
6. Reassemble the fifth wheel top plate to the slider base plate, if it was removed
previously.
